Inference on the Gamma Distribution
Technometrics, 2017This study develops inferential procedures for a gamma distribution. Based on the Cornish–Fisher expansion and pivoting the cumulative distribution function, an approximate confidence interval for ...

The Gamma–Kumaraswamy distribution: An alternative to Gamma distribution
Communications in Statistics - Theory and Methods, 2018ABSTRACTIn this article, a new generalization of the Kumaraswamy distribution, namely the Gamma–Kumaraswamy distribution, is defined and studied. Various properties of the Gamma–Kumaraswamy are obtained. The structural analysis of the distribution in this article includes limiting behavior, mode, quantiles, moments, skewness, kurtosis, Shannon’s ...

ABSTRACTA new two-parameter distribution, the gamma-Maxwell distribution, isproposed and studied. We generate the new distribution using the gamma-G generator of distributions. The proposal distribution can be seen as an extension of the Maxwell distribution with more flexibility in terms of the distribution asymmetry and kurtosis.

On the Inverted Gamma Distribution
, 2016If a random variable follows a particular distribution then the distribution of the reciprocal of that random variable is called inverted distribution. In this paper we studied some issues related with inverted gamma distribution which is the reciprocal ...

On the Lagrange gamma distribution
Computational Statistics & Data Analysis, 1998Statistical inference on the Lagrange gamma distribution is considered in this paper. The method of moments, the maximum-likelihood estimation technique, and the estimation of the scale parameter by order statistics are discussed. A linear rank test statistic is proposed for the distribution. A numerical example on the application of the Lagrange gamma

On Characterizations of Gamma Distribution
Bulletin of the Malaysian Mathematical Sciences Society, 2014Let \(X\) and \(Y\) be independent identically distributed nondegenerate and positive random variables with common absolutely continuous distribution function \(F(x)\). Put \(Z=\max (X,Y) \) and \(W=\min (X,Y)\). In this paper, it is proved that \(\dfrac{Z}{Z+W}\)\(\bigg ( {\mathrm{or}} \,\,\, \dfrac{W}{Z+W} \bigg ) \) and \(Z+W\) are independent if ...

An extension of the gamma distribution
Communications in Statistics - Theory and Methods, 2015ABSTRACTThe gamma distribution has been widely used in many research areas such as engineering and survival analysis. We present an extension of this distribution, called the Kummer beta gamma distribution, having greater flexibility to model scenarios involving skewed data. We derive analytical expressions for some mathematical quantities.
